Man's Search for Meaning has riveted generations of readers with its descriptions of life in Nazi death camps and its lessons for spiritual survival. Between 1942 and 1945 psychiatrist Viktor Frankl labored in four different camps, including Auschwitz, while his parents, brother, and pregnant wife perished. Based on his own experience and the stories of his many patients, Frankl argues that we cannot avoid suffering but we can choose how to cope with it, find meaning in it, and move forward with renewed purpose. Frankl's theory—known as logotherapy, from the Greek word logos ("meaning")—holds that our primary drive in life is not pleasure, as Freud maintained, but the discovery and pursuit of what we personally find meaningful. "What man actually needs," Frankl writes, "is not a tensionless state but rather the striving and struggling for a worthwhile goal, a freely chosen task . . . the call of a potential meaning waiting to be fulfilled by him."
